LIQUID-SEALED JAR.

Specification of Letters Patent.

. Patented I 1' cc. 16, 1913.

Application filed October 10, 1912. Serial No. 724,975.

T 0 all whom it may concern:

Be it known that I, lVILLiAM N. Moons, a citizen of the United States,residing at Pollard, in the county of luscanibia and State oi? Alabama,have invented certain new and nselul Improvements in Liquid-Sealed Jars;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention is a closure for jars or similar .rece itacles forpreserving and conserving :trnit, milk, wines and various other articlesof food, having for its object to provide an improved fluid seal betweenthe jar and its cover or covers.

In preserving some articles of food it is essential. that the jar shallbe rendered airtight, protecting the contents thereof from fermentationand contamination.

One object of the invention is to provide convenient means for sealingthe contents of the jar against contamination, wlhich sealing means will)ermit of the escape of gases which may be formed within the jar,

and at the same time preclude insects from gaining access to thecontents of the jar.

With these ends in view, the invention consists in providing the jarwith a peripheral channel, the outer wall of which is on a lower planethan the mouth of the jar, and a plurality of covers, one of which isadapted to be seated within the peripheral channel and contact with afluid sealing substance within the channel.

Other objects and advantages of the device will. become apparent fromthe following detailed description of the invention, taken in connectionwith the drawings.

In the accompanying drawing, I have illustrated one embodiment of theinvention, but the construction shown therein is to be understood asillustrative, only, and not as defining the limits of the invention.

Figure 1 is a side ehwation oi the jar, Fig. 2 is a vertical sectionalview through the jar, and Fig. 3 is an enlarged fragmentary view showinga portion of the central cover positioned within the ij eripheralchannel.

The jar may be composed of anv suitable material, such as pottery,glass, and the like. This jar is provided with a mouth (3, preterably ofless diameter than the body of the 'ar therebv formin a curved shoulder01'- tion 7 and an upstanding collar 8. The innor cover 9, having :1depending flange 10, [its over the mouth of the ar. This inner cover 1)may be of any suitable material, and

thereby producing a peripheral channel 13 adjacent the mouth oi. thejar. This flange 12 is shown as curved outwardly from the side wall, andthence upwardly, until the edge of the flange is substantiallyconcentric with the mouth of the jar. of this flange is on a lower planethan the upper edge oi the collar 8, forming the mouth of the jar,thereby precluding any liquid, which maybe poured into the channel 13,from flowing into the mouth of the Jar. The base oil the channel 13,which is in alinemcnt with the side walls of the jar, is provided withmeans serving as a seat 14 for an intermediate cover 1 aml in thedrawings this seat is shown rounded, as in so Fig. 3. The outer coverit) is adapted to engage, and lit: over, the top of the outer flange l2,and this top '16 may be provided with a peripheral groove l7, or anyother suitable means between the cover 16 and the flange 12.

The channel 1 is adapted to receive a suitable fluid for sealing thejar, and this fluid may be drawn oil from the channel,

when it is desired to gain access to the contents of the jar, by openinga port '18, adapted to be closed by any suitable means. In the drawings,I have shown the port closed by a stopper 1.5), but it is obvious thatany other means may be employed.

The various covers may be provided with any suitable means, as at 20,for handling the same. l urthermore, the jar 5 may be provided withsuitable means tl'or transporting it, such as the handle 2t ears 532.

Should. the cover it, become broken, or accidentally displaced fromposition, or should the flange 12 become broken sullicient to permit thefluid, or a portion there- 105 oil, to escape from the channel iii, thecovers 9 and 15 will serve to protect the contents of the jar. Evenshould the outer and i11 termediate covers 16, 15 become displaced fromthe jar, the inner cover 1) will serve to 11!) close the jar.

In operation, the artlclcs to be stored are The upper edge 70 'l'orproducing a tight joint 85 pivoted to the placed within the jar throughthe mouth 6, the cover 9 is alaced in position over the mouth 6, then te intermediate cover 15 is positioned over the inner cover 9 until theedge thereof engages the seat 1d of the channel 13. Any suitable fluidmay be poured into the channel 13 to seal the jar, care being taken thatport 18 is closed. The outer cover 16 may be placed in position toengage the top of flange 12, there'- by protecting the fluid fromevaporation, as well as from dust and contamination with injurioussubstances. In storing fermenting substances within the jar 5, the gasmay be permitted to escape from the jar into the chambers between theinner and central covers, or between the central cover and the outercover.

Having thus what I claim as new and Letters Patent, is:

1. In a device of the class described, a jar provided with a mouth, avflange concentric with tween the flange and mouth, a seat at the base ofthe channel, a cover adapted to engage the flange, another cover for themouth of the jar, and an intermediate cover adapted to rest in thechannel.

2. In a device of the class described, a jar rovided with a mouth ofless diameter than the body of the jar, a flange concentric withdescribed my invention, desire to secure by the mouth producing achannel bethe mouth of the jar, said flange being of greater diameterthan the body of the jar, and on a lower alane than said mouth, and aplurality of covers for the jar comprising an inner cover for the mouthof the jar, an intermediate cover adapted to rest on a seat in alinementwith the walls of the jar, and an outer cover adapted to engage saidflange.

3. In a device of the class described, a jar provided with a mouth ofless diameter than the body of the jar, a flange concentric with themouth of the jar of greater diameter than the body of the jar, saidflange forming a channel concentric with the mouth of the jar, a seat atthe base of the channel, and a series of covers for said jar, one ofsaid covers being provided with means for engaging the edge of theflange, another 01": said covers adapted to fit over the mouth of thejar, and an intermediate cover adapted to be positioned to rest upon theseat within the channel and in alinement with the side wall of the jar,whereby when fluid is placed within said channel, the intermediate coverwill contact with the fluid.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
